Questions about this item

What does the 166-piece count actually give me in the workshop?

You get 145 stainless-steel thread inserts, five HSS drill bits from 5.2 mm to 12.5 mm, five matching taps from M5×0.8 to M12×1.75, plus five installation tools, five break-off tools and a hex key.

Which metric thread pitches are covered by the included taps?

The taps cut M5×0.8, M6×1.0, M8×1.25, M10×1.5 and M12×1.75, matching the standard coarse pitches for those diameters.

What size case or drawer space does the 7.87 cm wide kit need?

The box measures 7.87 cm across, so it fits in a shallow toolbox drawer or on a pegboard shelf without crowding other tools.
